ORDER ANGIOSPERMIA. 133 



two species not uncommon in the middle states, in dry 

 fields, and stony grounds. The P. pubescens, pro- 

 ducing its purplish blue flowers about June ; the pu- 

 bescent leaves are lanceolate, oblong, sessile, and ser- 

 rulate ; the flowers in a thin panicle ; with the sterile 

 filament bearded above the middle. The P. Iceviga- 

 tum is very similar, but smooth, with paler, later flow- 

 ers, and is less common, except to the south. 



The Chelone, more common than the preceding 

 genus, at least the C. glabra, found in wet places, in 

 flower from August to October, is distinguished from 

 Pentstemou by the thick, short ventricose form of the 

 ringent corolla, in which the sterile filament is shorter 

 likewise than the rest ; the anthers are woolly, and 

 the seeds niembranaceously margined. The flowers 

 of the C. glabra are large and white, in dense spikes; 

 the leaves lanceolate, oblong, acuminate and serrate. 



** Calyx A-cleft. 



In wet meadows, about May and June, you will 

 sometimes observe a very gaudy, low, unbranched 

 plant of this class and order, to which some years ago, 

 with its congeners equally characterized, I gave the 

 name of Evchroma, nearly the vulgar appellation of 

 Painted-cup (probably an Indian name, as is that of 

 Red-bud, given to the Cercii). The common species, 

 here alluded to, E. coccinea, has the leaves and fine 

 scarlet bractes spread out, each into 3 wide divisions 

 like fingers on the stretch. The corolla is inconspic- 

 uous, of a greenish yellow, and bilabiate, with the 

 upper lip very long and linear, embracing the style 

 and stamens ; the calyx ventricose, 2 to 4-eleft ; 

 the anthers linear with unequal sized lobes, all of 

 them cohering together into the form of an oblong 

 disk; the capsule ovate, and compressed, 2-celled :
